Frequently Asked Questions
Can I replace my existing JIS 20K gate valve without altering the pipework?
Send the existing valve's nominal size, face-to-face dimension and mating flange details. Check the proposed drawing before approving a replacement; the JIS 20K designation alone does not confirm that all installation dimensions match.
Does JIS 20K give me one allowable pressure for every temperature?
Use the selected valve's approved pressure-temperature rating for its actual material and construction. Provide the process and design conditions with the inquiry rather than treating the designation as a universal operating-pressure limit.
Which JIS references should I include in my purchase specification?
Identify the required design, face-to-face, flange and inspection references separately. This page lists JIS B2071, JIS B2002, JIS B2220 and JIS B2003 for those roles; confirm the contractual editions and product-specific requirements before ordering.
